After semantic analysis, we now conduct the structure analysis to study the impact of prompt captions.
Similarly, we analyze the prompt structures from two angles, i.e., the length and the proportion of nouns in sentences.
The length of the sentence reflects the complexity of the sentence.
The proportion of nouns in the sentence affects the number of objects appearing in the fake image.
Here, we use NLTK [1]} to compute the proportion of nouns in a sentence.
